S9874^New	4-Aminobenzohydrazide 4-Aminobenzohydrazide (4-Aminobenzhydrazide, 4-aminobenzoic acid hydrazide, 4-ABAH, Myeloperoxidase Inhibitor I, NSC 640) is an inhibitor of MPO (Myeloperoxidase) enzyme that enhances iNOS induction in MPO-positive cells, but not in MPO-KO cells.
S5977^New	3-Amino-1,2,4-triazole 3-Amino-1,2,4-triazole (1,2,4-Triazol-3-amine, 3-AT, Aminotriazole, Amitrol, 3-Amino-1H-1,2,4-triazole, Trapidil impurity B) is a common irreversible inhibitor of catalase, induces a compensatory mechanism for the hydrogen peroxide detoxification, which includs a rise in glutathione peroxidase (GPX) and glutathione reductase activities.
S4452^New	ML162 ML162 is a covalent inhibitor of cellular phospholipid glutathione peroxidase (GPX-4) that induces ferroptosis.
S9803^New	Elamipretide (MTP-131) Elamipretide (MTP-131, SS-31, D-Arg-Dmt-Lys-Phe-NH2) is a cytochrome c peroxidase inhibitor. Elamipretide improves mitochondrial dysfunction, synaptic and memory impairment induced by lipopolysaccharide in mice.

S3298^New	Caulophylline (N-Methylcytisine) Caulophylline (N-Methylcytisine, Caulophyllin, NMC) is a tricyclic quinolizidine alkaloid with anti-inflammatory activities. Caulophylline binds to nicotinic acetylcholine receptors (nAChR) from squid optical ganglia with Kd of 50 nM. Caulophylline significantly reduces myeloperoxidase (MPO) activity, blocks the activation of NF-κB by inhibiting IκB and IKK phosphorylation.
S6822	TMB dihydrochloride TMB dihydrochloride (3,3',5,5'-Tetramethylbenzidine dihydrochloride hydrate, TMB-d, BM blue, Sure Blue TMB) is an excellent colorimetric substrate for detection of horseradish peroxidase (HRP) labeled probes and is used in staining procedures in immunohistochemistry and in enzyme-linked immunosorbent assays (ELISA).
